import axios from "axios";

export function request(config) {
  //1.创建axios的实例
  const instance = axios.create({
    baseURL: 'http://152.136.185.210:7878/api/m5',
    timeout: 5000
  })

  //2.axios的拦截器(有用)
  //2.1请求拦截的作用
  instance.interceptors.request.use(config => {
    return config
  }, err => {
    console.log(err);
  })

  //2.2响应拦截
  instance.interceptors.response.use(res => {
    return res.data
  }, err => {
    console.log(err);
  })

  //3.发送真正的网络请求
  //返回的是一个promise
  return instance(config)
}
